The focus of update 3.1.1 was introducing RED IPP2 workflow tailored color grading and monitoring LUTs. Update 3.1.1 allows you to apply LUTs directly on REDWideGamutRGB Log3G10 footage before making any conversion into Rec709 or P3.

Advantages of using IPP2 tailored LUTs

Moreover, as all your color edits take place in a wide standardized color space, should you later on (after your grade is finished) decide to go from Rec709 to P3 you would simply change the conversion LUT at the very end of your pipeline and all your color grading decisions would carry through!

There’s no more need to re-grade your footage for different outputs.

Additionally, by being able to apply LUTs directly on REDWideGamut Log3G10 footage, you can take advantage of the newest debayering and highlight algorithm improvements in the latest beta versions of REDCine-X software.

A quick example

Traditionally, you would first convert your log footage into a workable space such as Rec709 or P3. As this narrows the color gamut you’re working with, theoretically your edits could cause out-of-gamut colors which in turn cannot be displayed in your color space of choice.

While this is rare, and most color controls in various color grading software won’t go beyond gamut (and our LUTs make sure you don’t go out of gamut as well) it’s possible to loose information in your image if you’re not careful.

But what’s worse, as you’re applying the log conversion at the beginning of your pipeline, once you’re finished with the grade, it’s impossible to go from Rec709 to P3 and vice versa without regrading the footage.

IPP2 tailored LUTs change this.

As IPP2 LUTs are designed to work with REDWideGamutRGB Log3G10 footage, you apply them directly to your wide gamut standardized color space making sure no out of gamut edits can occur. More importantly, when working with IPP2 LUTs we leave the log conversion for the very end making the transition from Rec709 to P3 and vice versa seamless as all your color edits happen in REDWideGamutRGB before it’s narrowed down to Rec709 or P3.

With IPP2 LUTs simply change the log conversion LUT at the very end of your pipeline to go from Rec709 to P3 for example and you’re good to go.

Yes most definitely. The IPP2 workflow is in very simplified terms a new debayering of .r3d files so yes you can debayer any existing .r3d file using the new process. That new process however, requires a new kind of treatment and that’s where the IPP2 tailored LUTs come into game.

Unfortunately S-Gamut is not nearly wide enough to offer similar functionality. Additionally the number of possible permutations is too large to make it a viable product. We would have to maintain at least 4 separate sets of LUTs. Having said that, we have something very nice in our sleeves that will be dropping soon 🙂
